The aim of this study is to compare dose indices of various available protocols with different calculation and measurement methods. CT dose index (CTDI) in mGy is a measure of the radiation dose output of a CT scanner. A pencil ionisation chamber was used to measure dose index free air and in a standard CTDI phantom for different imaging protocols of HA and TrueBeam LINACs. For the point measurements, we found large deviations between displayed and calculated low CTDI values: 26.6 and 27.1% at Head low dose and Breast protocol, respectively. The calculated values were always larger than the displayed ones for all protocols and measurement setups. For the point measurements similar results were found as in the international literature, where the displayed values the measured CTDIs. true 2023 true true true false true false NONE 2026-10-23 false 4 0 4 2 2 4 4 4 4 4 4 2 2 2 2 0 4 2 4 2 0 3 3 Folyóiratcikk Journal Article 24 4 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2024 0 2 1 2 1 2025 0 2 1 2 1 Q3 false false false false 2023-06-04T11:12:30.336+0000 Nukleáris Technikai Intézet (BME / TTK);
